I suspect it is this above, since this is a one-time deal, only when a computer is set up for the first time (but done through the browser that one time). After that, it never asks for registration again unless the computer in question has not connected for months (in which case it has to be validated). > For some networks, you login via a browser, and it does some kind of > token exchange with their network that authorises you and they remember > some network details about you.

Also, I never store my cache so once the browser is shut down, the cache is deleted. Thanks very much again!
